Pet Vet Pet Food

This pet supply store also serves as a low-cost veterinary clinic.
It is owned by 2 of the best semi -retired vets on the planet, Marliss and karl.
There are veterinarians on duty (sometimes the dynamic duo, themselves) only on Sunday and Monday.

Whoever you get there, you can rest assured that you and your critter will be treated with respect, professionalism, and you will be charged very nominally for their services.

They provide very low cost vaccinations, and do basic exams, and simple treatments, and make referrals for more complicated procedures, x-rays, etc.
Additionally, their selection of foods and other supplies is wide and prices seem to be pretty competitive.

They also have a similar store / clinic on Potrero, in El Cerrito.
Please note: this is an unsolicited endorsement; I just want folks to know about this great, straight-ahead store / service.
